It is indeed a different Messi, not only from the one that saw his talents stifled somewhat by the more direct approach of Gerardo Martino but from the one that became peerless under the domineering era of Josep Guardiola. He is no longer the false nine but a player of imperious industry that is allowed licence to roam by Luis Enrique, starting to the right of a front 3 on paper but in reality moving to wherever his genius takes him.

The introduction of Luis Suarez to a frightening attacking triumvirate that already included Messi and Neymar led to Enrique having to discover a more creative role for the 27 year old and such a shift wasn’t without its issues. Back in January reports emerged of a training ground argument between Messi and Enrique which the club had to be quick to keep a lid on among boardroom upheaval and the possible sacking of the coach.

Rumours circulated over a potential move away from the Nou Camp for Messi as he was benched for the 1-0 defeat to Real Sociedad and the club were plunged into crisis, with the unthinkable exit of its brightest star now a stark possibility for the very first time.

In contrast Messi seems content, revelling in the role and form he is currently in. He failed to score in Wednesday’s victory over City but he claimed a beautiful assist for Ivan Rakitic’s winner and enjoyed making a mockery of the hapless James Milner and Fernandinho, much to the amusement of the on-watching Guardiola.

The nutmegs would take the headlines but the poise, grace and vision to reel City’s defenders over to his side of the pitch before finding Rakitic with a sumptuous cross-field ball was what mattered. Guardiola would return to Munich aware that Messi in this current form presents a huge threat to his Bayern team and their chances of winning back the Champions League title in Berlin in May.

As the Croatian found the net over the sprawling Joe Hart Messi got his 17th assist of the season to go with a 43 goals he has scored in all competitions. They are another round of extraordinary statistics that has seen records continue to be shattered. Currently out in front as Barcelona’s highest ever scorer with 397 at the relatively young age of 27, it is dismaying to imagine the numbers he could yet produce and the accolades he could yet achieve.

It is clear that Barcelona’s post-Sociedad soul searching was a huge watershed in their campaign, with both Andoni Zubizaretta and Carles Puyol exiting the club’s boardroom. Club president Josep Maria Bartomeu was forced into calling an early election for this summer to alleviate some of the tension surrounding the club and that, many believe, is key to Messi’s upturn in form and mood, the likely prospect of a summer break-up of the board he has recently grown disillusioned with.

To refer back to the tie with Manchester City and it would have been possible that, back in January, Manuel Pellegrini and co. would have been looking forward to the tie with Barcelona as clear opportunity to overcome their nemesis of last year. However Barca were to rediscover their vigour and City would leave Spain amidst talk of a significant summer upheaval with Sheikh Mansour’s billions once again ready to fund another recruitment drive with the emphasis on youth.

How much would they wish they could prise away their Nou Camp tormenter in chief who remains Barcelona’s prized possession, whom money simply can’t buy?
